1. Field of the Invention

The present invention relates to an image forming apparatus. More particularly, the present invention relates to an electronic album image forming apparatus having a scanner function.

2. Description of the Related Art

As the use of digital cameras and camera phones has expanded, there has been an increase in the demand for printing digital images at a user's home. To meet this demand, photo printers enabling the printing of digital images have been marketed.

However, a conventional photo printer requires being connected to a computer in order to print the digital images as photographed. That is, if the digital images photographed by the digital camera are transferred to the computer and a specific image among the transferred images is selected by using software installed in the computer, the photo printer prints the selected digital image onto a printing medium. However, having to always use a computer with a conventional photo printer is inconvenient to a user.

To solve the aforementioned problem, there has been developed a photo printer that enables the printing of digital images by directly connecting the printer to a digital camera.

However, this photo printer also has a problem in that it has no functions for a user to edit the digital image while viewing it and then print the edited image.

Moreover, conventional photo printers are not able to convert a printed picture into a digital image. Thus, it is inconvenient to a user that a scanner needs to be connected to the computer in order to convert the printed picture into the digital image.

Accordingly, there is a need for an improved image forming apparatus that doesn't require being connected to either a computer or a scanner.

As the album control portion 41, scan control portion 42 and print control portion 43 are already explained above, respectively, these will not be hereby repeatedly described.

The aforementioned electronic album unit 10, scan unit 20 and print unit 30 can be variously arranged in regards to the mutual relational position. However, preferably, the electronic album unit 10 may be arranged on the top, the scan unit 20 be arranged under the electronic album unit 10, and the print unit 30 be arranged as the lowest portion, as used in the exemplary embodiment of the present invention. Further, it is preferable that the opening portion 22 a of the scan unit 20 and the paper ejection opening 36 of the print unit 30 be arranged on the same side.

Now, the operations of the electronic album image forming apparatus 1 according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 5.

First, an operation of scanning an original document D by the scan unit 20 will be described below.

When a user feeds the original document into the first transfer roller 23 through the opening portion 22 a of the scan unit 20, the first original document-sensing sensor 28 disposed at the right of the first transfer roller 23 senses a front edge of the original document D (S10).

If the first original document-sensing sensor 28 senses the front edge of the original document D, it sends a signal to the scan control portion 42. Then, the scan control portion 42 drives the scan motor 45 to rotate the first transfer roller 23. When the first transfer roller 23 rotates, the original document D is transferred to the second transfer roller 24 along the guide portion 25 (S20).

After that, if the second original document-sensing sensor 24 senses the front edge of the original document D being transferred, it sends a signal to the scan control portion 42. Then, the scan control portion 42 scans the original document D by operating the lighting device 26 and the scan sensor 27 (S30). Herein, as the original document D is continuously transferred past the scan sensor 27 by the first transfer roller 23, the scan sensor 27 can scan the whole surface of the original document D.

If the original document D is continuously transferred and the first original document-sensing sensor 28 senses a rear edge of the original document D, the first original document-sensing sensor 28 sends a signal to the scan control portion 42. Then, the scan control portion 42 turns off the scan sensor 27 after a predetermined time. The predetermined time is determined passed on a distance between the first original document-sensing sensor 28 and the scan sensor 27. At this time, the scan control portion 42 stores the digital image that was scanned by the scan sensor 27 into the memory 17.

After that, if the second original document-sensing sensor 29 senses the rear edge of the original document D, it sends a signal to the scan control portion 42. At this time, the front part of the original document D is positioned at the second transfer roller 24. The scan control portion 42 receiving the signal from the second original document-sensing sensor 29 stops the scan motor 45 and again reverses it. Then, the first and second transfer rollers 23 and 24 are also reversed accordingly. If the first and second transfer rollers 23 and 24 operate in reverse, the original document D is transferred back inside the original document transfer path 22 to be transferred in reverse to the opening portion 22 a along the guide portion 25 (S40). That is, the original document D is transferred in the opposite direction to the transfer direction upon scanning and is ejected out of the scan unit 20. At this time, the first and second original document-sensing sensors 28 and 29 sense that the original document D is ejected and send a signal to the scan control portion 42 (S50). Then, the scan control portion 42 senses/perceives that the original document D is ejected, and stops the rotation of the first and second transfer rollers 23 and 24 to end the scanning operation (S60).

Next, an operation of viewing or editing the digital image by the electronic album unit 10 will be described.

The user displays the digital image stored in the memory 17 on the display portion 12 and selects a specific digital image by using the keypad portion 13 of the electronic album unit 10. In other cases, it is possible to select a desired image by automatically cycling the digital image displayed on the display portion 12.

In case of editing the image, after the image to be edited is displayed on the display portion 12, the displayed image is edited using the image editing software installed in the album control portion 41. Since the editing of the image by the image editing software is a known technique, this will not be hereby described.

When the editing of the digital image is completed, the user stores the edited image into the memory 17. If the user wants to print the edited image, the user can print the edited image onto the printing medium P by using the print unit 30.

Finally, an operation of printing the digital image on the printing medium P by the print unit 30 will be described. After displaying the digital image to be printed onto the display portion 12 by using the electronic album unit 10, the user loads the printing medium P in the paper feed tray 35. Then, the user can print the displayed digital image by pressing a print key on the keypad portion 13. Since the process of printing the digital image onto the printing medium P by the print unit 30 is similar to the process of printing using a conventional photo printer, this will not be hereby described.

The user can edit, by enlargement, reduction, composition and so on, the digital image displayed on the display portion 12 in a desired mode, and print the edited digital image using the print unit 30.

In addition, the user can scan the printed picture using the scan unit 20 and directly print it using the print unit 30.
